MACHINE FOR DOUBLING SILK, 86C.

SPECIFICATION forming part of Letter 5 Patent No. 277,074, dated May 8, 1883.

Application filed December 31, 1880. (Model.)

To all whom it may concern:

Be it known that I, GEORGE SINGLETON, a citizen of the United States, residing at Paterson, Passaic county, State of New Jersey, have invented a new and useful Improvement in Machines for Doubling Silk, 850., of which and 3, detail views of the stopping device,

Fig.4, a front view of the machine; Fig. 5, a view, partly in section, showing the flier and spindle and the pulleys thereof; and Fig. 6, a section on the line a; x of Fig. 5.

My invention relates to machines'for doubling strands of silk, c.

Referring to the drawings, A represents a metal frame which supports the driving mechzgznism and the various devices for doubling,

c. able bearings which are secured to the bottom rail of the main frame A. This shaftB is provided with the ordinary band-pulleys,b, to receive a belt which passes to the main drivingwheel. Adriving-cylinder,m,is'located on the shaft B, and, by means of a suitable belt, m,

(passing over the pulleys 411 actuates a counter-shaft, m. This shaft m is supported by and journaled in hangers m bolted to the under side of the top plate of the machine. The shaft B is also provided with a pinion, 0, that gears with wheel 0, which rotates on a stud, 0, secured to a hanger, 0 fastened to the frame A by a bolt, 0 The wheel 0' imparts motion to the cam-shaft 0" by means of pinion 0 which engages with gear-wheel 0 on the cam-shaft 0. The cam-shaft 0" is journaled in suitable bearings secured to the cross-rail of the main frame, and is provided with a cam, 12, for actuating the mechanism by means of which the spool Ois traversed. Arms or brackets Z are secured to the standards of frame A, and have j ournaled in them a shaft, l, to which is secured by a suitable set-screw a lever, l, which is provided with a roller, P, mounted on a stud, P secured to said lever l. A reciprocating motion is given to lever Z and shaft 1 by means of the cam 19, the inner end of the lever 1 being provided with a weight,

A driving-shaft, B, is journaled in suitn, which keeps said roller in constant engagement with the cam, thereby securing regularity of motion to the lever l and shaft I.

Secured to the ends of shaft l-by means of suitable set-screws are traverse-levers 7c, the upper ends of which are provided with slots k through which pass pins on the ends of a traverse-bar, W. The bar k is provided with a suitable hole in the center to receive the spindle k, the ends of which pass through bar R The spindle It has a nut on the end, and a collar formed on the inside of the bar k by means of which said spindle and bar are secured together. The spindle (having 'the channel or groove .2) passes through the standards 'r r, (secured to the top plate of the machine,) and the tube oftheflier, and has mounted on it a pulley, r. Said pulley has feather, 2, arranged therein,which en gages with the channel of the spindle and causes the spindle and dle to be traversed back and forth bymeans of the traversing mechanism. The tube of the flier a, which is jourualed in the standards 1, is providedwith a pulley, 1, for rotating the flier, which latter has formed on each of its forks eyes I), through which the strands pass to the receiving-spool. The counter-shaft 'm is provided with a pulleymz, to receive belts 1, that connect with the pulleys r r, and is also provided with the pulleys m (one of which is loose,) connected by a belt, m, with the driving-cylinder m, and the counter-shaft is actuated bysaid cylinder mthrough the intervention of the belt and pulleys just described. The jack-board a, secured to the main frame by brackets a, is provided with aseries of pins, 0 upon which are placed the supply-spools 0.

Above the jack-board, and in front of the machine, arms f are attached to the main frame to support a shaft, f, on which one or more fallers, e, are pivoted. The strands pass through these fallers in the operation of doubling. To prevent the fallers from falling forward on the loss of a strand, wire guards f secured to suitable brackets, f, on the main frame, are placed in front of the fallers, the strands from the supply-spools passing in front of the guards to the fallers. Brackets e are secured to the main frame above the pivotal points of the fallers, and have journaled in their ends a shaft, j", which carries a toothed pulley to turn together while allowing the spinwheel, g, and is rotated from the cam-shaft o", the'shaft f and cam-shaft being provided with suitable pulleys and a band for that purpose.

Secured to the main frame, above the wheel 9, are brackets y, in which a tripping-lever, g, is pivoted. This lever is provided with a catch, y, which engages with the toothed wheel 9 when the lower end of said lever is swung back in contact therewith by the dropping of a fal Ier when a thread breaks or is exhausted The rotation of said wheel, acting upon the said lever, actuates a pivotal catch, t, which is pivoted to a hanging bracket secured to the inside of the main frame. The pivotal catch t is provided with a latch end, it, in front, and is bent at right angles to the slide-bar h at the back, the bent end extending across the slidebar to enter the notch 7L2, formed therein. The slide-bar passes through the bracket to which the pivotal catch is secured, and rests in a slot formed therein. The back end of the bar It passes through and rests in brackets secured to the inside of the main frame. The front end of the slide-bar h is pivoted to an operatinghandle, 71/,which serves as a means for moving or adjusting the bar h. The slide-bar is provided with a suitable belt-shifter, w, for shifting the belt m when starting or stopping the flier a. and spindle is. A spiral spring, 8, is fastened at one end to the bar h, the opposite end being secured to the bracket that supports the end of the bar. Then the bar is drawn forward this spring is distended; but when a strand breaks and the pivotal catch it is'released from engagement with the bar It, the spring contracts and draws back the bar, and this action causes the belt-shifterw to shift the belt m from the fixed to the loose pulley on shaft m thereby stopping the shaft and flier a. On restoring the strand the operatinghandle It is pushed back, which action slides the bar It forward, and again places the spring s in tension, the end 23 of the catch t falls and causes the end t to enter the notch W of the I slide-bar h, which, as it comes forward again, shifts the belt 121/ from the loose to the fixed pulley, and sets in motion the spindle is and flier.

In operation the driving mechanism is put in motion in the manner before described. The strands are taken from the supply-spools 0, up past the wire f through the fallers 0, over the shaft d, which is carried by brackets d secured to the frame of the machine, and is rotated by a belt from the cam-shaft 0 through the eye I) of the flier to the receiving-spool, where the strands are laid evenly by the traverse mechanism, and are doubled while passing on the shaft 01. If a strand breaks the faller e falls back on the tripping-lever g,which throws the catch y into engagement with the toothed wheel 9, and the movement of the lever 9 backward by the action of said wheel 9 causes it to strike the end if of the pivotal catch t, and raises it, which action throws out the end it from engagement with lever h, which then, through the action of spring s, causes a stoppage of the machine, as before described.

Having thus described my invention, what I claim is The combination, substantially as before set .forth, with a flier, a spindle for carrying the receiving-spool, and mechanism for driving said flier and spindle independently of each other, of devices for carrying the supply-bobbins, the fallers, a tripping-lever, shaft f, tooth ed wheel g, carried thereby, notched slidebar h, pivoted catch t, having'latch t spring 8, and mechanism for rotating shaft f, and for imparting a longitudinal traverse to the receiving-spool spindle, substantially as and for the purpose set forth.

GEORGE SINGLETON.
